k750 camera issue = IMPORTANT = |

Hello guyz. I recently bought my k750i just about a month ago. I have been noticing the camera and encountered a problem. The camera takes photos but its not clean. It has some sort of dots/lines/noise and haziness which really disturbs the photo when taken in low lighting conditions. When in daylight these dots/lines/noise seem to fuse/blend with the brightness of the photo and it can be hardly seen. I have upgraded from the SE K700 to k750i. And for ur information i have noticed even more noise and haziness in k700i.
This is the current firmware Iam using:-
R1L002
CAMERA SW versions
Camera
Current:4.4
After I press the capture button the photo taken seems to become blurry and hazy. I hope you guyz can give me a proper explanation or a solution. Iam attaching a picture taken in very low lighting condition with flash off and night mode off (normal settings).
Please help! It will be nice to hear from u guyz.
This is another pitcture of my printer taken from the k750. What do u have to say about the indistinct quality?
Thanks for ur time
Cheers! |

Just check once if the camera lens is not dirty... if it is then clean with a cloth and try to click next pic..

no. iam not using night mode or flash. The dark photo is resized so the dots/lines/noise seem to be less. But you can see the picture of the printer is of very low quality with dots/lines/noise!

Not sure I understand the problem.
Its absolutely normal that pictures from digital cameras become noisy in low light conditions, its a fact of nature, and the reason why things like nightmode and flashes are invented, and why proffesional photographers setup big spots to light up the room when they need to take good indoor shots, even with pro equipment. Cameras takes pictures by letting light in through a lens, if there are no light or not enough light quality will suffer.
Also bear in mind that this is a cameramodule in a phone, a module which single value/cost is maybe only 10% of the entire cost of the phone. Imagine the difference between a 20-30$ cameramodule and a 300$ dedicated digicam, and how much you actually get out of that cameramodule in good conditions.
In short, lower your expectations to a reasonable level, your pictures look absolutely normal for a K750 or even a normal lower range digicam, considering the amount of avaliable light. Theres nothing wrong with your phone, if you can take good pictures in good natural lighting.
K750 takes fantastic pictures for a phone, under optimum lighting conditions, under low light conditions it cannot take fantastic pictures, but you can improve them alot by getting the add on flash if its important to you to take low light pictures.

numb. thank u for the kind words. but i just wanted to know if the picture quality in other k750 are the same or not. i know its not a digital cam but a part me me tells the quality should have been better. thanks again.
and guys does the firmware has anythin to do with this? |

Some have claimed it does - in the picture comparisons I've seen on esato I have never been able to satisfy myself that there is a difference between firmwares.
If anything, the early firmware R1A is better than the later firmwares, however if so the margin is so small as to be hard to really assess, especially without side by side photos of the same subject in the same low light conditions.
I believe the firmware could change things like what ISO the camera chooses for given conditions, but such choices are always compromises, for example higher ISO shots means more detail visible in lowlight, but also more grain in the picture.
The real cause of the lines you get in low light simply comes down to the limitation of the hardware. As numb says, this is to be expected of any digital camera in the same class as the K750.

k750i is not a digicam... i had the same pictures in low light conditions and it is pretty normal. that's the diff between a CMOS and CCD camera... but pictures in broad daylight is comparable with a digital camera

In a CCD sensor, every pixel's charge is transferred through a very limited number of output nodes (often just one) to be converted to voltage, buffered, and sent off-chip as an analog signal. All of the pixel can be devoted to light capture, and the output's uniformity (a key factor in image quality) is high.
In a CMOS sensor, each pixel has its own charge-to-voltage conversion, and the sensor often also includes amplifiers, noise-correction, and digitization circuits, so that the chip outputs digital bits. These other functions increase the design complexity and reduce the area available for light capture. With each pixel doing its own conversion, uniformity is lower.

K750i uses CMOS... with regards to image quality CCD is better...

generally true but the situation is changing. Some cmos chips are better quality than ccd counterparts. Some high end digital cameras are even getting cmos chips these days.. |

Buddy,if you want a phone with a better camera look no further then the N90.When there is enough light the little k750i takes pictures of about the same quality as the N90.Under all other circumstances the k750i camera is below standard.Don't listen to all the crap the 'experts' gives you.A cmos cam can/does take nice pictures at night too.(look at the legendary Nokia7650 night pic quality to see what I mean) the problem with the k750i lies in the digital processing which is applied to the picture after has been taken.This has to be done on a k750i because the camera is not that good and otherwise the pic quality will be crap day and night.Unfortunately digital image processing only works if yout have a 'acceptable' picture to begin with.

You can see in this comparison of both phones how "good" the N90 is under "all other circumstances"

Just play around a little bit with the settings and practice untill you get better results. The camera in the K750 is quite good.
